Recent studies have used import data to assess the impact of foreign varieties on prices and welfare for a home country. The reliance on import data has a number of limitations. First, these papers rely on goods categories defined by the Harmonized System. Second, they define varieties using the...

Modern trade models attribute the dispersion of international prices to physical and man-made barriers to trade, to the pricing-to-market by heterogeneous producers and to differences in the quality of output offered by firms. This paper presents a tractable general equilibrium model that...

We develop a theoretical model to study how changes in the durability of the goods affects prices of stolen goods, the incentives to steal and the equilibrium crime rate. When studying the production of durable goods, we find that the presence of crime affects consumer and producer surplus and...

We prove that in a closed economy without distortionary taxation, the welfare of a representative consumer is summarized to a first order by the current and expected future values of the Solow productivity residual in level and by the initial endowment of capital. The equivalence holds if the...

We study optimal product market interventions in an unequal economy in which firm ownership is concentrated and markups increase with firm market shares. We characterize optimal regulation in a static Mirrleesian setting in which we impose no constraints on the shape of interventions, and take...

A feature of many insurance markets is that they combine vertical differentiation (all consumers prefer high to low-coverage policies) and adverse selection (high cost customers prefer high-coverage plans). Building on Novshek and Sonnenschein (1978) and Azevedo and Gottlieb (2017), this paper...

It is well documented that retail prices in Japan are higher than in other countries for similar products. The two main competing explanations for this finding are: (1) a relatively high degree of discriminatory practices against imports and (2) relatively high distribution costs associated with...

Delays at the border for customs clearance are seemingly a central feature of the trade regime in the CIS states. Here, we argue that with queuing costs being endogenously determined in such circumstances tariff liberalization (even in the small economy case) can be welfare worsening since...

We view the political process in China as trading off the social benefits of increased trade and foreign direct investment, against the losses incurred by state-owned enterprises due to such liberalization. A model drawing on Grossman and Helpman (1994, 1996) is used to derive an empirically...
